Weakening demand for U.S. travel is prompting Canadian airlines to cut flights south of the border, with Air Canada canceling five routes for 2027. Data from aviation data and analytics company Cirium shows that the airline, Canada’s flag carrier and the largest in the country by fleet size and passenger volume, has cut its flights from Montréal to Seattle, Toronto to Boston and Charleston, and Vancouver to Nashville and Raleigh-Durham. The service between Toronto and Charleston, which the company started in March 2024, was the only Air Canada flight bringing Canadian snowbirds to South Carolina, one of the most popular U.S. states for their neighbors’ winter escapes.
These are the routes to U.S. destinations canceled by Air Canada next year: According to aviation website SimpleFlying, three of the routes were already suspended—from Montréal to Seattle, Vancouver to Nashville, and Vancouver to Raleigh-Durham—but were supposed to be reinstated in May 2027. However, all flights have now been removed. Flights from Toronto to Charleston, also already suspended, were supposed to start again in April next year, but they have been removed as well.
According to SimpleFlying, only 66.5 percent of seats on flights between the two destinations were filled between March 2024 and July 2026, falling from 67.8 percent in the first year of service to 62.1 percent in 2025, despite fewer flights and less capacity. An Air Canada representative confirmed the suspension of the seasonal flight to Charleston to TheStreet. On the other hand, Air Canada announced it will resume flights from Toronto to Kentucky’s Louisville Muhammad Ali International Airport (SDF), which were last available in 2002.
Newsweek contacted Air Canada for comment by email on Thursday morning. As Canadian travel to the U.S. remains under pressure from the simmering political tension between the Trump administration and the Canadian government and from rising fuel prices, other companies have already drastically reduced services to the United States. Westjet, Canada’s second-largest airline, has cut 10 U.S. routes this year, according to Cirium data cited by SimpleFlying.
Flights from Edmonton International Airport were the most affected, with services to Atlanta, Nashville, Chicago, Seattle and San Francisco halted this year. Flights between Edmonton and Nashville and Chicago were only operative for one season. The company also cut three routes between Vancouver International Airport and Boston, Nashville and Lihue, Hawaii, leaving the Canadian city without direct service to the latter.
WestJet also cut its nonstop service between Toronto Pearson and Los Angeles in April, and removed the service from Winnipeg to Nashville in May. Montréal-headquartered airline Air Transat ended all its flights to the U.S. by mid-June, which had been reduced by then to two destinations: Florida’s Fort Lauderdale and Orlando. Flights from Montréal to Orlando ended on May 3, while flights from Quebec City and Montréal to Fort Lauderdale ended between May and June.
